Failed update to 18.04, no GNOME or any desktop
Solution 1
The following list of actions solved the problem:
sudo apt-get update
sudo apt-get install ubuntu-desktop
sudo apt-get install gnome-core lightdm
sudo dpkg-reconfigure lightdm # select LightDM
then OP successfully logged in to the session.
Solution 2
It is very probably related to an online update that was rolled out yesterday by Ubuntu.
People who have been upgrading to 18.04 yesterday are experiencing it (I cannot boot normally after online update 23.8.2018 from 16.04 to 18.04)
People (like who) have been using 18.04 but applied the patch are experiencing it (Debian login screen after updating Ubuntu 18.04)
I had the same problem as you on the second screenshot. The GDM starts but somehow cannot finish loading. I also noticed errors with amdpro and radeon module loading in the kernel log.

I just updated to 18.04 from 16.04 and to 16.04 to 14.04 before that.
Anyway the 18.04 failed with an error saying something like gnome not installed and desktop depends on gnome. And it said it was going to recover, however it did nothing. After some time I restarted and the system. It came up with the desktop background but nothing else.
With Ctrl-Alt-F1 I am trying any commands I found without success.
Trying to install gnome I get missing dependencies. When trying to install
gnome-shell
and have a dependency forlibmutter-2-0
.I installed libmutter-2-0 but gnome-shell still reports it as a missing dependency.
I also don't have gdm3 or seemingly any other parts of gnome.
I have no idea what I am doing, I have been searching and running commands for installing anything I can find, but so far no success.
I would like to get some gui working or go back to 16.04 if possible.
Edit 1 After N0rbert's advice:
sudo apt-get update sudo apt-get install ubuntu-desktop
Did something in the sense that I can see my a desktop, but I only see a login button the the account, which instantly fails even before I have a chance to enter my password. Here are some screenshots: login failed after click
Crash screen In previous version I had it not require a password to login so I am surprised it is asking for one. Is it possible I just need to reset the password or authentication system?

N0rbert over 5 yearsPlease add error messages to the question. Something like output of
sudo apt-get update
,sudo apt-get install ubuntu-desktop
. -
MichaelE over 5 yearsThanks, after
sudo apt-get update
nowsudo apt-get install ubuntu-desktop
actually does something other than saying that there are missing dependencies. Not a single post mentionedsudo apt-get update
before the other commands. Should I try to restart now? -
N0rbert over 5 yearsTheoretically
sudo apt-get update
are launched periodically on its own. But for predictable results it is recommended to run it before installation of something. See this official documentation. If package installation is finished then you can reboot. The APT (package manager) is essential part of Debian and Ubuntu OS. You should learn it before use :) -
MichaelE over 5 yearsOf all the things I tried,
sudo apt-get install gnome-core
did a lot of stuff, but overall it did not help. Then with more searching for login issue I founddpkg-reconfigure lightdm
then i picked lightdm instead of gdm3 and after a restart I got the new desktop? Any ideas of what happened and anything else I might need to fix? Thanks again. -
N0rbert over 5 yearsgdm and lightdm are login-managers. If you do not ask to install new desktop, then you will have old one. So you will GNOME Shell with lightdm login screen. Can you login to graphical session?
-
MichaelE over 5 yearsYes, everything seems to be working fine with lightdm.

MichaelE over 5 yearsThank you, that is exactly it. Hopefully it saves someone else hours of troubleshooting.

mrnagydavid over 5 yearsThe solution above got me to a login screen, but I cannot actually log in (gnome crashes) and ctrl-alf-f* to another console crashes too, not even letting me to a shell.

ubuntu-desktop
fixes my System now.
